How to set specific location as an object's default (0,0,0)
I'm not exactly sure what you want to achieve, but if I understand it correctly, you want the camera to be the origin of an object? And the position of the object should be relative to the cameras position? If that is the case, use an empty at the cameras position, set it as a parent to the camera and all the corresponding objects. I'm not at my computer at the moment, so I can't try but it probably works if you set the camera as parent as well. All the best Marco
